drm/amdgpu: Return error if no RAS

2021-07-13T15:48:10Z

In amdgpu_ras_query_error_count() return an error if the device doesn't support RAS. This prevents that function from having to always set the values of the integer pointers (if set), and thus prevents function side effects--always to have to set values of integers if integer pointers set, regardless of whether RAS is supported or not--with this change this side effect is mitigated. Also, if no pointers are set, don't count, since we've no way of reporting the counts. Also, give this function a kernel-doc.

drm/amdgpu: Use delayed work to collect RAS error counters

2021-05-27T16:23:06Z

On Context Query2 IOCTL return the correctable and uncorrectable errors in O(1) fashion, from cached values, and schedule a delayed work function to calculate and cache them for the next such IOCTL. v2: Cancel pending delayed work at ras_fini(). v3: Remove conditionals when dealing with delayed work manipulation as they're inherently racy.

drm/amdgpu: Fix RAS function interface

2021-05-27T16:22:54Z

The correctable and uncorrectable errors are calculated at each invocation of this function. Therefore, it is highly inefficient to return just one of them based on a Boolean input. If the caller wants both, twice the work would be done. (And this work is O(n^3) on Vega20.) Fix this "interface" to simply return what it had calculated--both values. Let the caller choose what it wants to record, inspect, use.
